To all whom it may concern:

vBe it known that we, Gnonon P. BRAND and JOHN- SANTOS, citizen of the United States of Americaand subject of the King of Italy, respectively, and residents of New York, in the county andState of New York, have invented certain new and useful Im provements in Door and Pedal ()perating, Mechanism, of which the following is a specification. U

This invention relates to certain new and useful improvements in door and .pedalopcrating mechanism for pedal-operated .devices, such for'instance as piano playersand other automatic musical instruments.

It has for its objects among others to provide a simple yet efficient-and durable-and whereby the door and simultaneously and the pedals folded within the casing within minimum space, the door following the same and assisted to its closed position and there held by the means connecting the door with the pedals.

Another. object of the invention is to so construct and arrange the parts that the door shall told in one direction edals in the opposite direction, the door serving as the motive means for actuating the parts to throw the pedals in and out of the casing.

Another object of the invention is to construct the pedal. frame to allow of th'e compact folding of the parts one behind the other, and to allow or permanent connection between the parts.

Still a further object. is to so arrange the parts that tho pivotal point oi attachment oithev door with its connecting member shall be passed by the pivotal point oi connection with the pedal frame at its center just prior to the final closing of the door so canimovement its closed posidals are actuated to suddenly throw the door to tion after these pivotal point-s pass their po nt of crossing. The connections are such that the legs of the pedal frame are caused to assume substantially vertical position throughoutthe entire movement and cause them to fold in behind the door and against and the prior to the final olosingof the exhausters to .be entirely the door so as of the latter.

portioned and timed in their movements that there is 1110 conflict one with the other, and undue friction is avoided, so'tha't the their open or their closed position. The construction is such that the pedals serve to 'hold the .door in its open position an the door holds the pedals in their closed posi- LlOn.

We provide also an improved .form of pedal frame substantially U-shapedlat its center for the connection of the arm therewith at the center andat a point lowdown to close the :pedals within :the small space "provided.

' Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention, in its preferred form,'is clearly illustrated in the accompanying drawings, which, with the numerals of'reterence marked thereon, form a part oi this specification, and in which--- Figure 1 is a side elevation with the pedals and door in their open position. Fig. 2 is a trimuelmation with the parts inthe same position.

Fig. 4 is a diagrammatic View showing the relative positions-of the pivotal connections. the parts being iin icalotl as in their open position. Fig. 5 is a similar view with the parts indicated in their olosotl posit-hm. Fig. 6 is a. similar view showing the position of the parts 'just prior to the time the door assumes its all closed position, the pedals and their immediate connections being in substantially the same position with relation to the exhausters 'as they arein Fig.- 5'. Fig. '7 is a similar view showing the position of the parts and pivotal points when the door is partly closed and the pedals partly folded. V

The door may be closedand the pedals folded by a sudden quick movement of the door down ward, the momentum ofthe parts serving to take the pivotal points past the dead center with one movement. In opening the door, a quick movement upon the same by grasping the knob 12 serves to give initial impulse to thedoor and to the pedals and after the pivotal points have moved forward beyond the dead center, the weight of the 'pedals serves to assist in the opening movement, and when the parts assume the position indicated in Fig. 1, the weight of the pedals acts to hold the door in its open position and against closing.
